Precision Vise, also known as machine vise, are a kind of vise fixed on the machine tool table and used to clamp workpieces for cutting.

The main difference is that the nature is different, the structure is different, and the application is different, as follows：

1. Different nature

1. Bench vise

A bench vise, also known as a vise, is a universal fixture installed on a fitter's table to hold workpieces.
2. Flat-nose pliers

Flat-nose pliers, also known as machine vise, are a kind of vise fixed on the machine tool table and used to clamp workpieces for cutting.
2. Different structures

1. Bench vise

The structure of the bench vise is composed of a clamp body, a base, a guide nut, a screw, and a jaw body.The movable clamp body is slidably matched with the guide rail of the fixed clamp body through the guide rail.The screw is mounted on the movable pliers, which can be rotated, but cannot be moved axially, and cooperates with the screw nut installed in the fixed pliers.When the handle is shaken to rotate the screw, the movable clamp body can be driven to move axially relative to the fixed clamp body, which can act as a clamping or relaxing effect.

2. Precision Vise

The assembly structure of Precision Vise is a detachable threaded connection and pin connection, and the linear movement of the movable pliers body is transformed by spiral movement; the working surface is the friction surface of the spiral pair, the guide rail pair, and the shaft and hole with the gap.The composition of flat-nose pliers is concise and the structure is compact.

3. Different applications

1. Bench vise

It is an essential tool for the fitter workshop.

2. Precision Vise

Precision Vise are machine tool accessories used in milling machines, drilling machines, and grinding machines to hold workpieces.
